Tasha - I too have bad back pain and have been in tears a few times. And it does feel like its in my kidneys. I have a spray from the chemist and it works a treat. Also a warm wheat bag helps. When I have been sitting down and go to get up I get stuck and it takes ages for me to take that first step. I have been tested for uti as some of the girls on here suggested it may be that, but was all clear. Good luck at your ob appt. Hopefully he can shed some light on it.
